Is the modem/router from your Internet provider wireless or not ? Or it may be, but you use it in wired mode. Find out by calling their technical support. If it is not, exchange it for a wireless one from them. Should be free of charge.

Hope this helps.

Ensure that wireless isolation (or any labeled form of network isolation) is disabled, though it shouldn't be enabled unless it was manually set that way. I've also run into this issue when setting up Chromecasts occasionally, and I had to do a factory reset (hold down the small reset button on the Chromecast for 30 seconds) and repeat the setup process in order for it to be detected. You might try that as well.
